Golf practice assembly with multi target and trajectory

ABSTRACT

A golf practice assembly includes a first surface which has three target areas displayed thereon and the target areas are located in a vertical axis passing through a center of the first surface. A ball has a second surface which can be attached with the first surface of the golf practice assembly. The users use different golf clubs to send balls toward the first surface. The lower target area is designed for the lower number of golf club or for shorter distance between the position that the users stand and the first surface.

This is a Continuation-In-Part patent application of applicant's former patent application with application Ser. No. 11/703,125, filed on 7 Feb. 2007.

FIELD OF THE INVENTION Background of the Invention

A conventional golf practice assembly is disclosed in U.S. Pat. No. 3,601,406 which puts an image of green on a sheet of fabric and the user sends golf balls with hook-and-loop surface toward the sheet of fabric, the balls are then hooked on the sheet of fabric. Another U.S. Pat. No. 5,549,302 discloses a similar practice assembly as the U.S. Pat. No. 3,601,406, a more detailed image is put on the sheet fabric so that the user feels like playing on green. However, both of the two practice assemblies cannot provide a further function and cannot help the user to know the results of each swing. The conventional practice assemblies provide a basic function for the beginners to practice swing and there is no way to know the paths or angles that the balls are sent are correct or not.

The present invention intends to provide a golf practice assembly which includes a hook-and-loop surface with multiple target areas for different purposes and a ball with a hook-and-loop surface can be driven to be connected on the hook-and-loop surface. By the positions that the balls are attached on the hook-and-loop surface, the users obtain necessary information about the swinging.

SUMMARY OF THE INVENTION

The present invention relates to a golf practice assembly which comprises a first surface which has at least two target areas displayed thereon and the at least two target areas are located in a vertical axis passing through a center of the first surface. A ball has a second surface which is attached with the first surface of the target.

The primary object of the present invention is to provide a golf practice assembly wherein the user uses different golf clubs to send the ball to designated target areas and the balls can be attached on the surface of the golf practice assembly. By the positions that the balls are attached on the first surface of the practice assembly, the users realize the poses, the path that the balls fly and the grip on the golf clubs to be corrected.

Another object of the present invention is to provide a golf practice assembly wherein the target areas are located for different numbers of golf clubs.

Yet another object of the present invention is to provide a golf practice assembly wherein the target areas are located for different distances between the positions that the user stands and the golf practice assembly.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the golf practice assembly 10 of the present invention comprises a frame 13 and an analysis sheet is secured to a space enclosed by the frame 13. The analysis sheet includes a first surface 11 which is a hook-and-loop surface and has a target portion 12 displayed thereon, the target portion 12 is composed of three target areas 121, 122, 123. The target areas 121, 122, 123 are located on a vertical axis passing through a center of the first surface 11. A proper distance is defined between the target areas 121, 122, 123. The three target areas 121, 122, 123 are located at a high position, a mediate position and a low position on the first surface 11. The target areas 121, 122, 123 are designed and positioned for different numbers of golf clubs. Please referring to the FIG. 1, shown the target area 123 at the high position is for a higher number of golf clubs as 9 iron and the target area 122 at the middle position is for a number of golf clubs as 7 iron, a line between the target areas 122 and 123 is the number of golf clubs as 8 iron, above the target areas 123, their shown the position is for the golf clubs as PW and SW, the target area 121 at the low position is for a lower number of golf clubs as 5 iron, a line between the target areas 122 and 121 is the number of golf clubs as 6 iron, below the target area 121 at the lower, the line is for golf clubs as Wood Zone, every target area for the different golf clubs.

A ball 20 has a second surface 21 which includes a hook-and-loop surface and can be attached with the first surface 11 of the target 10. The ball 20 is made to have a weight that is within a range between 10 g to 43 g which is the weight range of the official golf balls. The first and second surfaces 11, 21 are designed to attach the balls 20 on the first surface 11.

The ball 20 should be sent to the target area 121 at low position when using a lower number of golf clubs. The ball 20 should be sent to the target area 123 at high position when using a higher number of golf clubs. A standard distance between the player and the golf practice assembly 10 of the present invention is 2.5 m.

The ball 20 can be attached on the first surface 11 of the golf practice assembly 10 of the present invention so that the user can check the accuracy of the path and angle that the ball flies. For example, the user uses a iron No. 7 golf club and aims the second target area 122 at a distance of 2.5 m from the golf practice assembly 10, if the ball hits the center of the second target area 122, this means the path of the ball 20 flies is correct. If the balls 20 are attached around the second target area 122 and spread randomly, this means the force to send the balls 20 are proper but the pose or the angle that the gold club relative to the balls 20 needs to be corrected. If the balls 20 attached on the first surface 11 are spread at high positions and low positions, this means the force to send the balls 20 is not correct.

The vertical axis passing through a center of the first surface 11, same as the “Center Aim”, beside right and left of the Center Aim, shown the “Right Aim” and “Left Aim”, their can help the user to target the first surface 11

By collecting and analyzing the results of the balls 20 on the first surface 11 of the practice assembly 10, the user can obtain a result which shows relationship between the pose, the force and the grip such that the user can correct his or her swing by the data. The vertical axis passing through the center of the first surface 11 is used to compensate or correct the visual error when aiming the targets 121, 122, 123.

The balls 20 are attached on the first surface 11 and do not bounce so that the practice assembly 10 is suitable for interior practice and does not damage objects nearby.

FIGS. 3 and 4 show another embodiment of the present invention, wherein the distance between the position where the user stands and the practice assembly 10 is changeable. The shorter the distance is, the lower the target area 121, 122, 123 are located. The longer the distance is, the higher the target area 121, 122, 123 are located. When the ball 20 is positioned at point “a”, the first target area 121 is to be aimed. When the ball 20 is positioned at point “b”, the second target area 122 is to be aimed. When the ball 20 is positioned at point “c”, the third target area 123 is to be aimed. There are patterns printed on the first surface 11 of the practice assembly 10.

By this practice assembly 10, the user can collect helpful data about the swing and correct his or her pose, force to send the balls 20 and the grip of the golf clubs. The balls 20 are attached on the first surface 11 of the practice assembly so that the present invention can be used inside or outside of rooms. The manufacturing cost for the practice assembly 10 is low while the data that is collected is helpful for correcting the swings.
